The ice load is the main control load of the offshore platform in the severe cold area， which has high requirements for the shear bearing capacity of the conduit leg of the offshore platform. In order to study the factors affecting the shear bearing capacity of concrete-filled steel tubular in stainless steel pipe offshore platform， a total of pieces were made
6Usage: it is widely used in automobile industry， aviation industry and other departments.
jKalambaThere is no argon protection on the back， and the flux cored wire + TIG process has been applied in China for several years. Flux cored wires such as et-elt-et-elt-t-et-elt- have been produced and have been used in the current industry
Chloride ions exist widely， such as salt，нержавеющая сталь sweat，Dipolog403 stainless steel sheetAnalysis of the status quo of the parts processing industry sea breeze soil and so on. Stainless steel corrodes rapidly in the presence of chloride ions， even more than ordinary low-carbon steel.
QNukualofaIt really affects the service life of the product. Today， I would like to share with you some precautions in the maintenance of stainless steel plate. Lets have a look!
DqThe width of coiled material is variable， clock spring and steel wire rope in aviation structure after deformation strengthening. If welding is required after deformation， only spot welding process and deformation can be used to increase the tendency of stress corrosion. And partial & gamma- M transformation to produce ferromagnetism， when in use
The test results are in good agreement On this basis， high-frequency welded stainless steel pipe can not be borne by chemical and nuclear industries， which is also one of the reasons.
FUse flux coated welding wire (self shielded welding wire) for backing TIG welding.
Vequipment maintenance Compared with traditional steel， stainless steel can not only ensure high strength and weight ratio but also have good plasticity，нержавеющая сталь toughness， formability and weldability. It is the first choice for making car frame. Stainless steel with superior performance can cause light weight and strong resistance
oNLow temperature embrittlement of stainless steel pipe --- in low temperature environment， the deformation energy is small. In the low-temperature environment， the phenomenon that the elongation and area shrinkage decrease is called low-temperature embrittlement. It is mostly produced on the body centered cubic structure of ferrite series.
. Surface defects of raw materials. Such as scratch， pitting， soaking， etc.
At low temperature， ferritic stainless steel pipe has low-temperature brittleness like carbon steel， while austenitic steel does not. Therefore， ferritic or martensitic stainless steel produces low-temperature embrittlement，нержавеющая сталь while austenitic stainless steel or nickel base alloy does not show low-temperature embrittlement. Of ferritic stainless steel pipe（
Fair pricerPoor， there will be obvious differences in material first.
ABecause its matrix contains Cr，Dipolog403 stainless steel sheetAnalysis of the status quo of the parts processing industry Ni and other alloy elements， the surface of stainless steel has strong passivation ability， which makes it have excellent corrosion resistance in many media，
Different heat treatment processes are used for heating and cooling stainless steel plates. For example， steel is heat treated for various commercial purposes. The common purpose of heat treatment is to improve strength， hardness， toughness， processability，нержавеющая сталь листовой, нержавеющая сталь рулон, нержавеющая сталь, нержавеющая сталь трубы, нержавеющая сталь стержни - китайская Тай - сталь сталь ооо formability ductility and other cold properties
wKalambaStructure. The physical properties of the film were characterized by nano indentation and microhardness measurement. The corrosion behavior and law of electroless plated PD samples on L stainless steel in medium and mixed acid medium were studied by corrosion coupon， polarization curve measurement and EIS
zKFace， stretch
To damage， it is called electrochemical corrosion.
